[0041] Example 1

[0042] This embodiment provides an insulating cover of a flat wire clamp, as shown in the attached Figure 1-7 As shown, including:

[0043] The main body 11 includes a wire cavity 12, a terminal board cavity 13, a first bolt cavity 14 and a second bolt cavity 15. The wire cavity 12 is connected to the terminal board cavity 13, and the wire cavity 12 and the terminal board cavity 13 are connected in the horizontal direction. The first bolt cavity 14 is connected to the upper end of the wire cavity 12, that is, the first bolt cavity 14 is located above the wire cavity 12, and the two are connected in the vertical direction. The second bolt cavity 15 is connected to the upper end of the terminal board cavity 13, that is, the second bolt cavity 15 is located above the terminal board cavity 13, and the two are connected in the vertical direction. The second bolt cavity 15 and the first bolt cavity 14 can be connected in the horizontal direction, or the second bolt cavity 15 and the first bolt cavity 14 can be not connected in the horizontal direction. In this embodiment, the second bolt cavity 15 and the wire cavity 12 are connected horizontally, that is, the wire cavity 12 is horizontally connected to the terminal board cavity 13 and the second bolt cavity 15. The wire cavity 12 is provided with a circular opening 121, and the circular opening 121 is not located at the same height as the first bolt cavity 14, that is, the circular opening 121 is not connected to the first bolt cavity 14 in the horizontal direction. When the bolt is connected and fixed to the flat wire clamp 16, the bolt moves horizontally and cannot be moved out of the circular opening 121 to the outside. Here, the circular opening 121 is used for the external wire to extend into the wire cavity 12 to achieve the fixing effect between the external wire and the flat wire clamp 16. The terminal board cavity 13 is provided with a rectangular opening 131, and the rectangular opening 131 is not located at the same height as the second bolt cavity 15, that is, the rectangular opening 131 is not connected to the second bolt cavity 15 in the horizontal direction. When the bolt is connected and fixed to the terminal board 17, the bolt moves horizontally and cannot be moved out of the rectangular opening 131 to the outside. Here, the rectangular opening 131 is used for fixing the terminal board 17 and the cooperation between the external wire and the terminal board 17. The wire cavity 12 accommodates the flat wire clamp 16. The terminal board cavity 13 accommodates the terminal board 17. Here, the flat wire clamp 16 and the terminal board 17 are electrically connected, and the two can be independent of each other, and then the electrical connection effect is achieved through a conductive member. Alternatively, the flat wire clamp 16 and the terminal board 17 can be integrally formed to form an electrical connection effect. Those skilled in the art can adjust according to actual needs. Through the setting of the first bolt cavity 14 and the second bolt cavity 15, the fixing effect of the bolt is formed. When the bolt is fixed with the flat wire clamp 16 and the terminal board 17 respectively, due to the limitation of the height difference, the bolt, the flat wire clamp 16, and the terminal board 17 are restricted in the horizontal direction to prevent separation from the insulating cover.

[0044] Specifically, as attached Figure 1-7As shown, it also includes an insulating pin 18. The main body 11 is bent to form a wire cavity 12, a terminal board cavity 13, a first bolt cavity 14 and a second bolt cavity 15. The main body 11 is bent to form a structure that is approximately a rectangular parallelepiped. The bending positions of the main body 11 are all flexible connections, and a connection will be formed after bending. In this embodiment, the connection of the main body 11 is located on the long side wall, specifically in the middle area of ​​the long side wall, that is, it is similar to a long strip structure. A locking hole 19 is provided at the connection of the main body 11, and the insulating pin 18 passes through the locking hole 19. The insulating pin 18 is used to achieve the fixing effect of the main body 11 after bending, further improving the fixing strength and preventing it from falling off and separating. In addition, the main body 11 can also be two parts, and the two parts are spliced ​​to form a corresponding chamber.

[0045] Specifically, as attached Figure 1-6 As shown, the main body 11 is provided with two edge sealing parts 111, and the edge sealing parts 111 extend horizontally toward the outside, and the edge sealing parts 111 have no correlation with the wire cavity 12, the terminal board cavity 13, the first bolt cavity 14, and the second bolt cavity 15. The two edge sealing parts 111 are fitted together to form the connection of the main body 11, and the locking hole 19 is provided in the edge sealing part 111. The provision of the edge sealing part 111 further improves the fixing effect. When the two edge sealing parts 111 are fitted together, the fixing effect is formed by the insulating pin 18. The number of locking holes 19 here can be adjusted according to actual needs, and can be distributed at equal intervals or in other distribution methods, as long as the fastening effect is guaranteed.

[0046] Specifically, as attached Figure 7 As shown, the insulating pin 18 includes an inverted cone 181. The inverted cone 181 specifically means that the lower end of the insulating pin 18 has a conical structure, and the connection between the inverted cone 181 and the rest of the insulating pin 18 forms a step structure. The top surface size of the inverted cone 181 is larger than the size of the locking hole 19. Due to the elastic effect, the inverted cone 181 can pass through the locking hole 19. When the inverted cone 181 cooperates with the locking hole 19, a barb fixing effect is formed, thereby improving the fixing level of the insulating pin 18. It should also be noted here that the insulating pin 18 is made of insulating material, which can be plastic or other materials.

[0047] Specifically, as attached Figure 1-6 As shown, the body 11 is further provided with a placement groove 20, which is connected to the lower end of the wire cavity 12 and the lower end of the terminal board cavity 13. A through leakage hole 201 is provided on the bottom surface of the placement groove 20. With the arrangement of the placement groove 20 and the leakage hole 201, even if water drops penetrate into the interior of the insulating cover, under the action of gravity, the water will flow into the placement groove 20 and then be discharged through the leakage hole 201.

[0048] Specifically, as attached Figure 1-6As shown, the width of the placement slot 20 is smaller than the width of the wire cavity 12 and the terminal board cavity 13. The width of the placement slot 20 is limited to form an upper and lower separation effect to prevent the flat wire clip 16 and the terminal board 17 from falling into the placement slot 20.

[0049] Specifically, as attached Figure 5 As shown, the flat wire clamp 16 also includes a torque nut 161, which is accommodated in the first bolt cavity 14. The torque nut 161 is arranged so that after the tightening is completed, the torque nut 161 will partially fall off, thereby making the installation torque constant, improving the tightening effect, and preventing loosening.

[0050] Specifically, as attached Figure 1-6 As shown, the wire cavity 12 includes a frustum portion 122, and the circular opening 121 is located at the frustum portion 122. It should be noted here that the frustum portion 122 is a circular opening 121 that gradually increases toward one side of the guide cavity, that is, the circular opening 121 is at the smallest position. The setting of the frustum portion 122 forms an effect of clamping the wire, further improving the protection level.

[0051] Specifically, the circular opening 121 and the rectangular opening 131 are not coaxially arranged, and specifically, the circular opening 121 and the rectangular opening 131 are not located at the same height. By setting different axes, different height fixing effects are formed, that is, a height difference is formed, which improves the firmness of the fixing. In this embodiment, the circular opening 121 is located at the upper left end of the entire insulating cover, and the rectangular opening 131 is located at the lower right end of the entire insulating cover.

[0052] Specifically, the material of the body 11 is flame retardant silicone rubber. The flame retardant silicone rubber material makes the entire insulation cover not only have the effect of insulation protection, but also have flame retardant, waterproof and other effects. The insulation cover is mainly used to protect the flat wire clamp 16, the exposed part of the wire, and the equipment outlet terminal board 17. It is waterproof, flame retardant, and voltage-resistant, and forms an insulation layer to play an insulation protection effect.

[0053] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
